Trachinotus carolinus (Linnaeus). (" Pompano.") 



Two examples taken in the pound, September, 1901. 

 POMATOMIDiE. 

 Pomatomus saltatrix (Linnseus). ("Blue Fish.") 



These are taken by trolling in the Rips— Muskeget Rip, Great Point 

 Rip and Bass Rip (off Sankaty Head)— and for many years great 

 numbers were caught by boats in the opening which broke through 

 some fifty years ago between Nantucket and Tuckernuck. This place 

 is now given up. When the bluefish first became common about the 

 island, in the early 60's, they were caught in the harbor, now they 

 are rarely seen there. Set-nets were also used, but of late these are 

 but little used. The Petrel gets them off the south and east ends of 

 the island by means of sweep-nets. When a school is seen— and this 

 can be done at some distance by the terns which hover over them— 

 the net is shot from dories and pulled around the school, the fish in 

 darting away get gilled and are then taken from the net. 



"Heaving and hauling"— i.e., throwing a drail or leaded hook from 

 the shore and hauling in— is now occasionally done at the south shore, 

 and on September 26, 1903, an example weighing 27 pounds was taken. 

 This is considerably larger than the largest heretofore reported by 

 Jordan and Evermann, Food and Game Fishes, 1902, p. 321, where one 

 weighing 22 pounds and measuring 3 feet in length is mentioned. 



Up to 1880 hundreds were often caught in an afternoon from the 

 south shore. 



C BNTROL OPHID^. 

 *Palinuriclitliys peroiformis (MitchiU). (" Rudder Fish.") 



STROMATEID^. 

 *Rhombus triacanthus (Peck). (" Butter Fish." "Butter Scup.") 



These have never been known to take a hook. All the specimens are 

 taken in the pounds, as many as twenty barrels having been obtained 

 in a day. The first taken in 1904 was on May 6, and two the next day. 



PERCID^. 



Perca flavescens (MitchiU). (" Pond Fish." "Perch.") 



Only taken in the fresh-water ponds, and very abundant. 



SERRANID^. 

 Roccus lineatus (Bloch). ("Striped Bass.") 



Rarely taken on the scup grounds.
